如果我把注释（ # ... ）放在我的Makefile中， make会给我一个错误并退出。 如果我删除评论，生成文件工作正常。
Makefile:1: *** missing separator. Stop.
Makefile：

你的Makefile适合我（用空格替换空格），所以听起来你有一个流浪的非打印字符的情况。
尝试检查“ cat -vet Makefile ”的输出。 这将显示EOL，TAB和其他看不见的字符。
你会想看到这样的事情：
# Backup Makefile$ #$ # Create backups from various services and the system itself. This$ # script is used to perform single backup tasks or a whole backup$ # from the system. For more information about this file and how to$ # use it, read the README file in the same directory.$ $ BACKUP_ROOT = /srv/backup$ ETC_PATH = /srv/config$ SVN_PATH = /srv/svn/$ TRAC_PATH = /srv/trac/sysinventory$ PR10_PATH = /swsd/project/vmimages/...$ PR10_MOUNT_PATH = /tmp/temp_sshfs_pr10$ $ MYSQL_USER = "xxx"$ MYSQL_PASSWORD = "xxx"$ $ $ DATE = `date +%F`$ $ help :$ ^Icat README$ $ $ init-environment :$ ^Imkdir -p $(BACKUP_ROOT)$ ^Imkdir $(BACKUP_ROOT)/tmp$ ^Imkdir -p $(PR10_MOUNT_PATH)$ $
确保所有命令都以“ ^I ”开头。
你也可以尝试使用类似的东西寻找流浪的字符：
cat -vet Makefile | grep "\^[^I]" --colour=auto
您可能使用了空格而不是制表符来进行评论。 请发布生成文件，所以我们不必猜测。
